Where this position leads
Condition: Cholesterol (LDL, HDL and Total)
What the study found
Who was studied 434,646 British ancestry individuals, 8,796 British Central/South Asian individuals, 6,573 British African individuals.
The effect Each copy of the T allele shifted the measure 0.02 % higher (95% confidence interval 0.02-0.02); p = 3 × 10−16.
Where it sits Chromosome 19, band 19p13.11 — in an intron of MAST3.
rs66464318 is a single position in the genome, in or near the MAST3 gene. Published research associates it with triglycerides to total lipids in chylomicrons and extremely large vldl percentage. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
On MyGeneLog this position is linked to Cholesterol (LDL, HDL and Total). The research behind each link, and its sources, are set out on that condition page.
No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.
